Description

[Technical Field]

[0001] The present invention relates to bedding with a fan, which includes a bedding body and a fan. [Background technology]

[0002] Bedding made of a three-dimensional network structure has been known in the past. For example, Patent Document 1 below proposes a mattress made of a three-dimensional network structure with a spring structure made of hollow wires. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-245287 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the mattress of Patent Document 1 has the problem that heat and moisture accumulate in the flat three-dimensional network structure, resulting in poor comfort. Furthermore, the mattress of Patent Document 1 has a certain weight due to the structure of the three-dimensional network structure, so it cannot be used as bedding other than a mattress. Furthermore, the mattress of Patent Document 1 has a certain hardness due to the structure of the three-dimensional network structure, so it is difficult to fold for storage, and if it were flexible enough to be foldable, it would be difficult to support the user.

[0005] The present invention was devised in consideration of the above-mentioned circumstances, and its main object is to provide a fan-equipped bedding that is lightweight, comfortable, foldable, and capable of supporting the user. [Means for solving the problem]

[0006] The present invention is a bedding with a blower, which includes a bedding body and a blower, wherein the bedding body includes at least one pillar-shaped bedding element, the bedding element having an outer cover member formed from a fabric material and a filling material arranged inside the outer cover member, and at least one of the filling materials has a flat cross-sectional shape in the longitudinal direction.

[0007] In the bedding of the present invention, it is desirable that the outer cover member is not breathable, and the inner material includes a cushion member and an air circulation layer disposed inside the cushion member.

[0008] In the bedding of the present invention, it is desirable that the air blower blows air into the interior of the bedding element.

[0009] In the bedding of the present invention, the bedding elements preferably include one first element and two second elements arranged side by side at a distance between both longitudinal ends of the first element.

[0010] In the bedding of the present invention, it is desirable that one longitudinal end of the second element is connected to the first element, and the blower is provided at the other longitudinal end.

[0011] In the bedding of the present invention, the outer cover member is preferably formed integrally with a first outer cover member covering the first element and a second outer cover member covering the second element, and the cross-sectional shape of the first outer cover member in the longitudinal direction when the blower is operated and inflated is preferably equal to the cross-sectional shape of the second outer cover member in the longitudinal direction when the blower is operated and inflated.

[0012] In the bedding of the present invention, the filling material includes a first filling material arranged in the first element and a second filling material arranged in the second element, and it is desirable that the cross-sectional shape of the first filling material in the longitudinal direction is circular, and the cross-sectional shape of the second filling material in the longitudinal direction is an oval shape having a major axis and a minor axis.

[0013] In the bedding of the present invention, the major diameter of the second filling material is preferably 115% to 150% of the minor diameter of the second filling material. [Effects of the Invention]

[0014] In the fan-equipped bedding of the present invention, the bedding body includes at least one pillar-shaped bedding element. Because the pillar-shaped bedding element is used, this bedding body is lightweight and provides excellent comfort.

[0015] In the fan-equipped bedding of the present invention, the bedding element has an outer cover member made of a fabric material and a filling material disposed inside the outer cover member, with at least one of the filling materials having a flat cross-sectional shape in the longitudinal direction. Because the filling material of this bedding element is flat, it has a large contact area with the surface on which the user sleeps during use, preventing misalignment and supporting the user. Furthermore, this bedding element can be easily folded in the direction of its short axis when stored. Therefore, the fan-equipped bedding of the present invention is lightweight and comfortable, and is both foldable and able to support the user. [Brief explanation of the drawings]

[0017] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 is a perspective view showing the fan-equipped bedding 1 of this embodiment, and Fig. 2 is a plan view of the fan-equipped bedding 1 of Fig. 1. As shown in Figs. 1 and 2, the fan-equipped bedding 1 of this embodiment includes a bedding body 2 and a fan 3 provided in the bedding body 2.

[0018] The bedding body 2 of this embodiment includes at least one pillar-shaped bedding element 4. Because the bedding element 4 is pillar-shaped, this bedding body 2 is lightweight, flexible, and comfortable. Therefore, the blower-equipped bedding 1 of this embodiment can reduce the overall weight and can be used as multi-purpose bedding such as a mattress, a comforter, a pillow, or a body pillow.

[0019] Here, flexibility means softness and is an index evaluated by the hardness when the surface is pressed, and comfort is an index evaluated comprehensively by the user based on factors such as heat and humidity while sleeping, the feeling of pressure, and the feel on the skin.

[0020] Fig. 3 is a cross-sectional view taken along line AA in Fig. 2. Fig. 3 schematically shows wrinkles and sagging that occur in the outer cover member 5. As shown in Fig. 3, the bedding element 4 of this embodiment has an outer cover member 5 made of a fabric material and an inner material 6 disposed inside the outer cover member 5. The inner material 6 is, for example, surrounded by the outer cover member 5 and forms the core of the bedding element 4.

[0021] At least one of the fillings 6 of this embodiment has a flat cross-sectional shape relative to the longitudinal direction. The bedding element 4 is preferably placed on the bedding surface so that the minor axis of the flattened filling 6 is vertical when in use. Because the filling 6 of this type of bedding element 4 is flat, it has a large contact area with the bedding surface on which the user sleeps during use, preventing misalignment and supporting the user. Furthermore, this bedding element 4 can be easily folded in the minor axis direction of the flattened filling, as shown by the two-dot chain line in Figure 1, when stored. Furthermore, this bedding element 4 can exert a certain degree of rigidity in the major axis direction of the flattened filling, allowing it to adequately support the user. Therefore, the fan-equipped bedding 1 of this embodiment is lightweight and comfortable, and is both foldable and user-supporting.

[0022] In a more preferred embodiment, the fan 3 is provided in at least one of the bedding elements 4. Such a fan 3 can circulate air inside the bedding element 4 and remove heat and moisture accumulated inside the bedding element 4, thereby improving the comfort of the fan-equipped bedding 1.

[0023] Fig. 4 is a perspective view of the fan-equipped bedding 1 when the fan 3 is operating, and Fig. 5 is a cross-sectional view of Fig. 3 when the fan 3 is operating. As shown in Figs. 4 and 5, the fan 3 of this embodiment is configured as a suction fan that sends outside air into the bedding element 4. The bedding element 4 preferably has an outer cover member 5 that expands when the fan 3 is operated.

[0024] Such bedding element 4 allows the air flow to be visually recognized by the expanding outer cover member 5, further improving the comfort of the fan-equipped bedding 1. Furthermore, since such outer cover member 5 expands to allow air to flow, flow resistance is small, allowing a large amount of air to flow with a small fan 3, which helps to reduce the weight of the fan-equipped bedding 1.

[0025] However, the fan-equipped bedding 1 is not limited to this embodiment, and may be one in which the air inside the bedding element 4 is exhausted by the fan 3, for example. Even in such fan-equipped bedding 1, by flattening the inner material 6, the contact area with the bed surface on which the user sleeps during use is large, preventing displacement and supporting the user. This has the effect of being easy to fold in the direction of the short diameter of the flattened shape, and exhibiting a certain degree of rigidity in the direction of the long diameter of the flattened shape.

[0026] As shown in Figures 1 to 5, the outer cover member 5 of this embodiment is formed from a non-breathable fabric material. Examples of non-breathable fabric materials include recycled fibers, synthetic resin fibers, natural fibers, blends, etc. that have been windproofed. Examples of recycled fibers include cellulose and rayon. Examples of synthetic resin fibers include polyester and nylon. Examples of natural fibers include cotton and silk. Examples of blends include a blend of polyester and cotton.

[0027] Examples of windproofing include lamination and downproofing. The outer cover member 5 of this embodiment is made of rayon that has been downproofed. The outer cover member 5 may also be made of a polyester and cotton blend that has been downproofed. Such an outer cover member 5 allows air to circulate efficiently when the fan 3 is activated, which helps to reduce the weight of the fan-equipped bedding 1.

[0028] The outer cover member 5 is formed, for example, from a non-stretchable fabric material. In this case, the outer cover member 5 is in a contracted state with wrinkles and sagging, for example, when the blower 3 is not operating. With such an outer cover member 5, it is easy to determine the shape it will assume when it is expanded by operating the blower 3, and it can be easily expanded by a small blower 3. Note that the outer cover member 5 may also be formed, for example, from a stretchable fabric material.

[0029] It is desirable that the outer cover member 5 has a substantially cylindrical shape when inflated by operation of the blower 3. Such an outer cover member 5 can flexibly support the user when the blower 3 is in operation and in use, thereby improving the comfort of the blower-equipped bedding 1.

[0030] The outer cover member 5 is preferably configured to be detachable using opening forming means (not shown) such as wire fasteners or hook-and-loop fasteners. The opening forming means extends, for example, along the longitudinal direction of the bedding element 4. Such an outer cover member 5 can be removed and washed, thereby improving the comfort of the fan-equipped bedding 1.

[0031] When the opening forming means is a wire fastener, the outer cover member 5 preferably has a protective strip (not shown) that covers the opening forming means. Such an outer cover member 5 prevents the user from coming into contact with the hard part of the wire fastener when using the fan-equipped bedding 1, further improving the comfort of the fan-equipped bedding 1.

[0032] The filling 6 of this embodiment includes a cushion member 7. The cushion member 7 is made of, for example, synthetic cotton, natural cotton, etc. Examples of synthetic cotton include polyester resin cotton, etc. Examples of natural cotton include cotton, etc. Such a cushion member 7 has excellent flexibility and breathability. The cushion member 7 is not limited to this embodiment, and may be made of, for example, urethane foam, beads, etc., as long as it is flexible and breathable.

[0033] The external shape of the cushion member 7 is, for example, substantially the same as the external shape of the bedding element 4 when the fan 3 is not operating. The cushion member 7 of the filling 6 having a flat cross section in the longitudinal direction is preferably formed in a flat cylindrical shape, and the cushion member 7 of the filling 6 having a circular cross section in the longitudinal direction is preferably formed in a cylindrical shape. The cushion member 7 has, for example, a substantially constant thickness t in the cross section in the longitudinal direction. Such a cushion member 7 can provide excellent flexibility and comfort.

[0034] The filling material 6 of this embodiment includes an inner cover member 8 that covers the cushion member 7. The inner cover member 8 is preferably disposed between the outer cover member 5 and the cushion member 7. The inner cover member 8 is formed from a synthetic resin such as polyester or nylon. The inner cover member 8 preferably has greater breathability than the cushion member 7. Such an inner cover member 8 protects the highly flexible cushion member 7, improving its durability, and does not affect the good breathability of the cushion member 7.

[0035] The inner cover member 8 is formed, for example, from a mesh member such as a three-dimensional textile structure. Examples of three-dimensional textile structures include three-dimensional knitted fabrics and three-dimensional woven fabrics. Examples of three-dimensional knitted fabrics include a three-dimensional mesh structure and a double Russell structure. Examples of three-dimensional woven fabrics include a three-dimensional multi-layered woven fabric. The inner cover member 8 is desirably formed so that its outer diameter shape forms the outer diameter shape of the filling 6. Such an inner cover member 8 helps to protect the cushion member 7 and improve its durability without affecting the breathability of the cushion member 7.

[0036] The inner material 6 of this embodiment includes an air flow layer 9 disposed inside the cushion member 7. The air flow layer 9 is preferably formed from a space through which air can flow or from a material with low air flow resistance. The air flow layer 9 of this embodiment is an air flow member 10 formed from a fibrous three-dimensional structure or a three-dimensional network structure.

[0037] Examples of three-dimensional textile structures include three-dimensional knitted fabrics and three-dimensional woven fabrics. Examples of three-dimensional knitted fabrics include three-dimensional mesh structures and double Russell structures. Examples of three-dimensional woven fabrics include three-dimensional multilayer woven fabrics. A three-dimensional network structure is, for example, a structure formed from resin wires that are irregularly entangled in a three-dimensional shape. Such an air flow member 10 has an appropriate self-shape retention ability and can maintain the shape of the core material 6 while ensuring an air flow path when the blower 3 is operated.

[0038] The cross-sectional shape of the air flow member 10 perpendicular to the longitudinal direction is preferably approximately similar to the cross-sectional shape of the core material 6 perpendicular to the longitudinal direction. An air flow member 10 for a core material 6 having a flat cross-sectional shape in the longitudinal direction preferably has an oval cross-sectional shape, and an air flow member 10 for a core material 6 having a circular cross-sectional shape in the longitudinal direction preferably has a circular cross-sectional shape.

[0039] The air flow member 10 of this embodiment has a solid shape in which a three-dimensional fiber structure or a three-dimensional network structure is disposed all the way to its center. The air flow member 10 is not limited to this form and may, for example, be hollow, or may be a polygonal column or polygonal tube as long as the cross-sectional shape perpendicular to the longitudinal direction is flat. When the air flow member 10 is hollow, the air flow resistance can be reduced, just as when the air flow layer 9 is empty.

[0040] The air flow member 10 is formed, for example, by extrusion molding resin wires that form a three-dimensional network structure. The air flow member 10 is preferably formed into a columnar shape as a whole when the resin wires that have been extruded in a three-dimensional, irregularly entangled state are cooled. For example, if the air flow member 10 is cylindrical, the extruded resin wires are cooled and solidified into a columnar shape. Such an air flow member 10 does not require additional processing, improving productivity.

[0041] As shown in Figure 5, the outer cover member 5 of this embodiment expands when the blower 3 is operated, forming the air-blowing layer 11. Such an air-blowing layer 11 has low flow resistance, allowing a large amount of air to circulate with a small-sized blower 3. Furthermore, because this air-blowing layer 11 is formed by the outer cover member 5 that comes into contact with the user, it can efficiently discharge heat and moisture generated by the user.

[0042] The air-blowing layer 11 of this embodiment contracts to the state shown in Fig. 3 when the operation of the air blower 3 is stopped. That is, the outer cover member 5 of this embodiment has wrinkles and sagging when the air blower 3 is not operating, and when the air blower 3 is operated, air flows into the interior like a windsock, eliminating the wrinkles and sagging and forming the air-blowing layer 11.

[0043] It is desirable that the air-blowing layer 11 be configured to allow air to pass through it and the air-flow layer 9 via the inner cover member 8 and the cushion member 7. Even if such an air-blowing layer 11 is partially blocked by the user or an external factor, air can still pass through the air-flow layer 9 downstream of the blocked part. Therefore, even if the bedding element 4 of this embodiment is partially compressed from the outside and the air-blowing layer 11 is blocked, the outer cover member 5 downstream of it can be expanded, thereby improving the comfort of the fan-equipped bedding 1.

[0044] 1, 2, and 4, the bedding element 4 of this embodiment includes one first element 12 and two second elements 13 arranged side by side at a distance between both longitudinal ends 12a of the first element 12. As a result, the bedding body 2 of this embodiment is formed in a Π shape as a whole.

[0045] Since the first element 12 and the second element 13 are each pillar-shaped, the bedding element 4 can be used as multipurpose bedding such as a mattress, a comforter, a pillow, a huggable pillow, etc. In this specification, the longitudinal direction of the first element 12 may be referred to as the left-right direction, and the longitudinal direction of the second element 13 may be referred to as the front-rear direction.

[0046] The longitudinal ends of the bedding element 4 include, for example, both left-right end portions 12a of the first element 12 and one end portion 13a and the other end portion 13b of the second element 13 in the front-rear direction. The bedding element 4 is preferably used so that the first element 12 side faces the head of the user and the other end portion 13b of the second element 13 faces the legs of the user.

[0047] The first element 12 preferably has a ventilation section 14 for discharging air at at least one of both longitudinal ends 12a. Such a first element 12 can discharge internal air through the ventilation section 14, thereby suppressing the accumulation of heat and humidity and providing excellent comfort. Furthermore, this ventilation section 14 can prevent the discharged air from directly hitting the user, further improving the comfort of the fan-equipped bedding 1.

[0048] Fig. 6 is a cross-sectional view taken along line BB in Fig. 2. As shown in Fig. 6, the first element 12 of this embodiment is not provided with a blower 3. The first element 12 of this embodiment is provided with ventilation sections 14 at both end sections 12a. This type of first element 12 is excellent in quietness because the blower 3 is not provided near the user's head.

[0049] As shown in Figures 1, 2 and 4, the second element 13 of this embodiment has one longitudinal end 13a integrally connected between both ends 12a of the first element 12, and a blower 3 is provided at the other end 13b.

[0050] Such second element 13 can expand outer cover member 5 and visualize the inflow of air by sending external air from blower 3 into second element 13. In addition, this second element 13 has excellent quietness because blower 3 is provided at the other end 13b that is farthest from the user's head.

[0051] Fig. 7 is a cross-sectional view taken along line CC in Fig. 2. As shown in Figs. 1, 2, 6, and 7, the outer cover member 5 of this embodiment is formed by integrally forming a first outer cover member 5A that covers the first element 12 and a second outer cover member 5B that covers the second element 13. Therefore, the air-blowing layer 11 of the first element 12 and the air-blowing layer 11 of the second element 13 are in communication with each other. In this type of outer cover member 5, air sent from the air blower 3 provided in the second element 13 can inflate the first outer cover member 5A via the second outer cover member 5B, further improving the comfort of the fan-equipped bedding 1.

[0052] It is desirable that the cross-sectional shape in the longitudinal direction of the first outer cover member 5A when it expands due to operation of the blower 3 be equal to the cross-sectional shape in the longitudinal direction of the second outer cover member 5B when it expands due to operation of the blower 3. In such an outer cover member 5, the first element 12 and the second element 13 expand to the same size, further improving the comfort of the fan-equipped bedding 1.

[0053] 7, the outer cover member 5 has, for example, a mounting washer 5a for mounting the blower 3 to the other end 13b of the second element 13. The mounting washer 5a is preferably made of a washable material, such as resin. Such an outer cover member 5 makes it easy to mount and remove the blower 3, and is also easy to use because there is no need to remove the mounting washer 5a from the outer cover member 5 when removing the blower 3 and washing the outer cover member 5.

[0054] The blower 3 includes, for example, a blower blade (not shown) rotated by an electric motor, a case 3a that houses the electric motor and the blower blade, and a fixing ring 3b for attaching the blower 3 to the mounting washer 5a. The blower 3 is preferably connected to an external power source via an electric cord, a controller, etc. (not shown).

[0055] The case 3a is formed with, for example, a flange 3c for clamping the mounting washer 5a in cooperation with the fixing ring 3b. Such a blower 3 is easy to install and remove, can be easily removed when washing the outer cover member 5, and is also easy to maintain.

[0056] As shown in Figures 6 and 7, the filling 6 of this embodiment includes a first filling 6A arranged in the first element 12 and a second filling 6B arranged in the second element 13. The cross-sectional shape of the first filling 6A in the longitudinal direction is, for example, circular. The diameter of the first filling 6A is, for example, equal to the major axis d1 of the second filling 6B described below. This type of bedding body 2 has no corners in the area that comes into contact with the user, even when the first element 12 is used as a pillow, improving the comfort of the fan-equipped bedding 1.

[0057] 6, the first core 6A of this embodiment includes a first cushion member 7A, a first inner cover member 8A that covers the first cushion member 7A, and a first air flow layer 9A disposed inside the first cushion member 7A. The first air flow layer 9A is preferably a first air flow member 10A formed from a fiber three-dimensional structure or a three-dimensional network structure. The first air flow member 10A is formed, for example, in the shape of a solid cylinder.

[0058] The first inner cover member 8A preferably has first inner ends 8a that cover the longitudinal ends of the first cushion member 7A. In this embodiment, the first inner ends 8a are provided on both end portions 12a of the first element 12. This first inner cover member 8A can protect the first cushion member 7A as a whole even when the outer cover member 5 is removed.

[0059] The first inner end 8a is disposed, for example, adjacent to the ventilation portion 14. This improves the rigidity of both end portions 12a of the first element 12 of the first outer cover member 5A, and eliminates the need for members to maintain the shape of both end portions 12a, which helps to reduce the weight of the fan-equipped bedding 1.

[0060] The air permeability of the first inner end 8a is preferably greater than that of other parts of the first inner cover member 8A. The first inner end 8a is formed, for example, from a mesh member. Such a first inner cover member 8A has low air flow resistance at the first inner end 8a, allowing air to flow smoothly between the first inner end 8a and the interior of the first inner cover member 8A.

[0061] As shown in Figures 3 and 5, the cross-sectional shape of the second filling 6B in the longitudinal direction is an oval shape with a major axis d1 and a minor axis d2. The cross-sectional shape of the second filling 6B in the longitudinal direction may be, for example, an oval shape with a flat surface in the major axis direction, or an ellipse. When the second element 13 is used, the contact portion is an arc, even when the user comes into contact with the second filling 6B, thereby improving the comfort of the fan-equipped bedding 1.

[0062] The major axis d1 of the second core 6B is preferably 115% to 150% of the minor axis d2 of the second core 6B. When the major axis d1 of the second core 6B is 115% or more of the minor axis d2, it is easy to fold in the minor axis direction while maintaining rigidity in the major axis direction. When the major axis d1 of the second core 6B is 150% or less of the minor axis d2, the blowing layer 11 is prevented from becoming excessively large, and the blower 3 that inflates it can be made smaller.

[0063] The second element 13 preferably has an outer diameter d4 when the second outer cover member 5B is expanded that is 125% to 200% of the minor diameter d3 when the second outer cover member 5B is not expanded. Here, the minor diameter d3 when the second outer cover member 5B is not expanded is measured when the second outer cover member 5B and the second inner material 6B are in contact with each other.

[0064] By making the outer diameter d4 when inflated 125% or more of the minor diameter d3 when uninflated, it is possible to ensure a sufficiently large air-blowing layer 11. By making the outer diameter d4 when inflated 200% or less of the minor diameter d3 when uninflated, it is possible to prevent excessive inflation that would compress the user, and it also helps to make the air blower 3 that inflates it smaller.

[0065] 5, the second element 13 of this embodiment has an inner diameter d5 of 105% to 125% of the major diameter d1 of the second inner material 6B when the second outer cover member 5B is expanded. Such a bedding element 4 can reliably ensure the required volume of the air-blowing layer 11.

[0066] As shown in Figures 3, 5, and 7, the second core 6B of this embodiment includes a second cushion member 7B, a second inner cover member 8B that covers the second cushion member 7B, and a second air flow layer 9B disposed inside the second cushion member 7B. The second air flow layer 9B is preferably a second air flow member 10B formed from a fibrous three-dimensional structure or a three-dimensional network structure. The second air flow member 10B is formed, for example, in the shape of a solid flattened cylinder.

[0067] As shown in Fig. 7, the second inner cover member 8B preferably has a second inner end 8b that covers the longitudinal end of the second cushion member 7B. In this embodiment, the second inner end 8b is provided on the other end 13b side of the second element 13. Although not shown, the second inner end 8b may also be provided on one end 13a (shown in Fig. 1) side of the second element 13. This second inner cover member 8B can protect the second cushion member 7B as a whole even when the outer cover member 5 is removed.

[0068] The second inner end 8b on the other end 13b side of the second element 13 is disposed, for example, at a distance L from the end of the blower 3. This allows the second outer cover member 5B to provide a chamber 5b at the other end 13b of the second element 13, and allows the blowing layer 11 (shown in FIG. 5) to be smoothly formed.

[0069] The air permeability of the second inner end 8b is preferably greater than that of other portions of the second inner cover member 8B. The second inner end 8b is formed, for example, from a mesh member. Such a second inner cover member 8B has low air flow resistance at the second inner end 8b, allowing air to flow smoothly inside the second inner cover member 8B.

[0070] As shown in Figures 6 and 7, it is desirable that the first cushion member 7A and the second cushion member 7B are formed from the same material. In this embodiment, the first cushion member 7A and the second cushion member 7B have the same thickness t. Such a cushion member 7 can improve productivity and reduce production costs. However, the first cushion member 7A and the second cushion member 7B may be formed from different materials with different thicknesses t.

[0071] The first inner cover member 8A and the second inner cover member 8B are integrally formed by a fixing means such as sewing, welding, etc. In this inner cover member 8, the first cushion member 7A and the second cushion member 7B can be handled as an integral unit.

[0072] The first air flow member 10A and the second air flow member 10B are preferably made of the same material. Such an air flow member 10 can improve productivity and reduce production costs. However, the first air flow member 10A and the second air flow member 10B may be made of different materials.

[0073] 1, 2, and 4, the bedding body 2 preferably includes a connecting member 15 for connecting the two second elements 13. The connecting member 15 of this embodiment connects the other end portions 13b of the two second elements 13. The connecting member 15 includes, for example, a strip-shaped portion 15a and ring-shaped portions 15b formed on both longitudinal sides of the strip-shaped portion 15a.

[0074] The connecting member 15 of this embodiment connects two second elements 13 by inserting the second elements 13 into the ring-shaped portion 15b. The connecting member 15 is preferably made of a non-stretchable fabric material. The connecting member 15 may be fixed to the second elements 13 by a fixing member (not shown) such as a button, hook, or hook-and-loop fastener. Such a connecting member 15 can prevent the other end portions 13b of the second elements 13 from being separated by more than a predetermined distance.

[0075] The ring-shaped portion 15b in this embodiment has a size that allows for an outer diameter d4 (shown in FIG. 5) when the outer cover member 5 expands as the blower 3 operates. Such a connecting member 15 prevents the air-blowing layer 11 (shown in FIG. 5) from becoming smaller, and there is no risk of impeding the smooth flow of air.
